Ironically, Branson’s company once won a court case determining that ‘bollocks’ was not, in fact, vulgar.

UK police had taken Virgin Records to court after they displayed The Sex Pistols’ iconic album Never Mind the Bollocks in the storefront.

According to police, it was too vulgar because ‘bollocks’ was a derivative of the word ‘testicles’.

But Branson brought a linguistics professor in as a witness to testify that it was actually a nickname given to priests in the 18th Century.

Of course, Virgin’s email filters are about to receive an adjustment.

“Craig loved the story, and is getting his IT team to correct the email block so we can all continue to use the word bollocks in the future,” wrote Branson.

And maybe the policy change will be for the better, since a study by the University of East Anglia found swearing at work can reinforce solidarity amongst staff, and generally has a positive effect.

"Certainly in most scenarios, in particular in the presence of customers or senior staff, profanity must be seriously discouraged or banned," advised professor of management Yehuda Baruch.

“However, our study suggested that in many cases, taboo language serves the needs of people for developing and maintaining solidarity, and as a mechanism to cope with stress. Banning it could backfire."

He added: "Managers need to understand how their staff feel about swearing. The challenge is to master the ‘art’ of knowing when to turn a blind eye to communication that does not meet their own standards."
